I find myself in need a suit capable of taking a severe amount of working. I've recently taken on a sales position that involves quite a bit of physical activity: running up and down stairs, carrying heavy objects and a general need for lots of mobility. The question being, is there a particular sort of material that is best suited to this? Am I best served with a typical wool suit, or would a different material such as cotton be better for this environment? I just can't bring myself to get a cheap spandex/polyester/cotton/wool blend, I don't like the look or the feel-- or the durability for that matter. Any suggestions would be greatly appreciated!
